In this guide, we will help you solve the Authentication Failed issue when using the WooCommerce FedEx Shipping Plugin. We will also show you how Shopify FedEx App authenticates the FedEx credentials. Read along to know more.

How to authenticate FedEx credentials when using WooCommerce FedEx shipping plugin?

With WooCommerce FedEx Shipping plugin installed on your WooCommerce, you can link your FedEx Account and handle shipping. You can display FedEx shipping rates on your Cart/Checkout page, print FedEx shipping labels, enable order tracking, and so much more.

When do you get the Debug Error: “Authentication Failed”?

The plugin works with FedEx APIs and you need a valid FedEx Account to use it. If you don’t have a valid FedEx account, you won’t be able to make use of certain features like label generation. And you will get the error Debug Error: “Authentication Failed” every time you use an invalid account.

A real-life example

To help you understand the severity of this error, we would ask you to go through the conversation below. Here, one of our customers was facing a similar issue and our support team helped him overcome it.

Customer

Hello. After activating the WooCommerce FedEx shipping plugin, everything seems to work as it should for small orders. In other words, the customer only sees the Flat rate shipping rate.

If I try an order for more than twenty books, instead of a drop-down menu, the customer is presented with a note that says “There are no shipping methods available. Please double check your address, or contact us if you need any help.

With debug turned on, the FedEx response says “Authentication Failed”. I had configured your plugin with the same account number, password, keys, etc., by copying and pasting from the old plugin. But apparently, that did not work for the account authentication. Could you please help me?

Errors like the “Authentication Failed” appear only when the FedEx credentials are not correct. This happens at times

  • when you’re using invalid FedEx credentials
  • when you’re using FedEx Test/Development credentials but have checked the “This is a production key”
  • you have the FedEx Production/Live credentials with you but you haven’t checked the “This is a production key”

So we request you to check the credentials in the plugin settings. You can begin here if you don’t have the right credentials with you.
